How Do You Spell DIASTOLIC COUNTERPULSATION?

Pronunciation: [dˌa͡ɪəstˈɒlɪk kˈa͡ʊntəpəlsˈe͡ɪʃən] (IPA)

Diastolic Counterpulsation is a medical term that refers to a procedure that uses a device to supplement the heart's blood pumping action. The word "Diastolic" is pronounced /daɪəˈstɒlɪk/, with the stress on the second syllable. It refers to the phase of the heart cycle when the heart muscle relaxes and fills with blood. "Counterpulsation" is pronounced /kaʊntəˌpʌlsˈeɪʃən/, with the stress on the second syllable. It means the action of using an external device to assist the heart in pumping blood during the cardiac cycle.

DIASTOLIC COUNTERPULSATION Meaning and Definition

1. Diastolic counterpulsation refers to a medical technique or therapeutic intervention used to assist and improve cardiac function, specifically during diastole, which is the relaxation phase of the cardiac cycle when the heart chambers fill with blood.

   During diastolic counterpulsation, a device is typically employed to generate a counterpulsation or counterbalance effect to the heart's natural pumping action. This device is often an inflatable balloon or cuff that is placed in the aorta, the largest artery supplying oxygenated blood to the body. The balloon inflates during diastole, the period when the heart muscle relaxes, causing it to apply gentle pressure on the aorta and compress the bloodstream. This compression enhances coronary artery perfusion, the process by which the heart's own blood vessels receive oxygen and nutrients.

   The primary objective of diastolic counterpulsation is to increase coronary blood flow, aid myocardial oxygenation, and relieve the workload on the heart by promoting effective blood supply to the cardiac muscle. By enhancing diastolic blood flow and reducing cardiac workload, this technique aims to improve cardiac output, decrease peripheral vascular resistance, and mitigate the symptoms of heart failure or other cardiac conditions.

   Diastolic counterpulsation is most commonly utilized in the setting of advanced heart failure, acute myocardial infarction (heart attack), and refractory angina (chronic severe chest pain), when traditional medical management alone may not be sufficient. It is typically performed under close medical supervision and may require an implantable device or an external apparatus for continuous therapy.

Etymology of DIASTOLIC COUNTERPULSATION

The word "diastolic counterpulsation" is derived from two main components:

1. Diastolic: The term diastolic comes from the Greek word "diastole", which means "a stretching out". In the medical context, diastole refers to the phase of the cardiac cycle when the heart's chambers relax and fill with blood.

2. Counterpulsation: Counterpulsation is a compound word formed from the prefix "counter-" and the noun "pulsation". The prefix "counter-" means "against" or "opposite". Pulsation, on the other hand, derives from the Latin word "pulsatio", meaning "a beating or pulsing action".

When combined, "diastolic counterpulsation" refers to a medical technique used to assist the heart in pumping blood during the diastolic phase by delivering counter pulses of external pressure to the aorta.
